" Application filed February 19, 1897. Serial No. 624,254. (No model.)

To all whom, it many/,l concern:

p Be it knownthat LWILLIAM HENRY KnLso, a citizen of the United States,residing at Butte7 in the county of Silver Bow and State of Montana,have invented certain new and useful Improvements in Miners Picks; and Ido declare the following to be a full, clear, and exact description ofvthe invention, such as will enable others skilled in the art to which itappertains to make'and use the same.

My invention has relation to improvements in miners picks; andtlie'object is to provide the pick with a detachable point.

To this end the novelty consists in the construction, combination, andarrangement of the same, as will be hereinafter more fully described,and particularly pointed out in the claim.

In the accompanying drawings the same reference-characters indicate thesame parts of the invention.

Figure 1 is a perspective view of my improved mining-piek. Fig. 2 is alongitudinal section of one of the arms and point, and Fig.

3 is a horizontal section of the same.

1 represents the eye, and 2 2 the integral arms. The outer ends of thesearms are each formed with a longitudinal rectangular socket 3, the sidewalls Ll 4 of which are parallel to each other, while the top and bottomwalls 5 5 gradually converge from the shoulder 6 inwardly toward theeye.

7 represents a circular orificel extending through the top and bottomwalls.

9 represents the detachable point, and it is provided with an integralrectangular shank 10, formed with a shoulder 12 and parallel sides 13and 14, while the top and bottom sides 15 and 16 converge from theshoulder to the end of the shank. The shank itself conforms exactly inshape to the socket 3, which it snugly fits. y

An orifice 17 in the shank 10 is slightly curved longitudinally and outof alinement with the corresponding orifice in the socket, so that whenthe pin 18 is inserted it bends to conform to the curved orifice 17,forming a kink and making it impossible for its accidental withdrawal.

Having thus described my invention, what I claim as new and useful, anddesire to secure by Letters Patent of the United States7 1s- A minerspick comprising the eye 1, the integral arm 2 formed with the socket 3having orifices 7, in combination with the detachable point 9 having theintegral shank 10 provided with the longitudinally-curved orice 17 andthe Ypin 18, whereby when the shank 10 is inserted in said socket andits inner end 'abutting against the end wall thereof and the pin Vdriventhrough the orices 7 and V17, a portion of the said pin will be bent orknocked out of alinement with the orifices 7, substantially as setforth.

In testimony whereof I hereunto affix my signature in presence of twowitnesses.

WILLIAM HENRY KELSO.
